Thanks for the thought.. I'm just gonna hafta go with the wait..
EDIT: 20th March - We are up to-
"The ECU worked out OK. no immobilizer key needed. great!!
The Traction control and Stability Control lights are on because those system don't work without the SMT. Are you OK for us to permanently disable those lights?. As per prior emails, the car drives as it should and ABS appears fully functional
We are working on some small changes to make a better reverse selection "feel". The part i wanted from Toyota is still 10 days away, so we are trying to improvise
The tailpipe is damaged/hanging down because the back part of the exhaust has been damaged at some time. i suspect it was due to the extra "low". With your approval i'll sort that out."
